The first thing you need to do is to have full faith. 100% believing that you will achieve your goal. This may sound very straight forward but you will be surprised that how frequent you let negative thoughts creep into your mind. An in my opinion, this is the first and most difficult hurdle that you will face in achieving your goals. You must be very determined and very consistent in "cleaning up" your mind to ensure you have a very healthy and strong mind.
Take the first step now clean up all the negative beliefs and just simply said that you will achieve your goals. Even though you do not believe it now, it is alright. Just keep telling yourself 2 times everyday. In the morning when you wake up and at night before you sleep. And tell yourself that you will dream of success when you sleep. Start to think about what you will be doing when you have achieved your success. If you are thinking of being wealthy, then, think of what you will do when you have achieved that. What kind of house and what kind of cars etc. If you are thinking of helping people, imagine how the people who received your help will react. How their face will be beaming with lights of hope and how you greet them and how they greet you etc.
The next thing is to condition your mind for success. This is very logical step to do. In the first place, you mind is not aware of what you want to do. Don't think that your mind knows what you are thinking. Your mind actually has different "department" just like in a big business organisation that you work for. One department may not be aware of what the other department is doing unless there is communication. So, you need to communicate with different parts of the mind so that everyone is moving towards the same goal. At the same time, you mind has not been trained to do the task. You need to train it. You need to condition it. Your mind need to be prepared for it. So key conditioning steps will be given in the due course.
